Amprius Technologies is trading 8.03% up at $12.90 after no new, clearly attributable company-specific catalyst was identified for August 14, 2026.
- The latest disclosed company news was an August 13 lease amendment extending the Fremont facility through June 2034.
- The amendment involves approximately $10.5 million in future payments, but reporting does not directly connect it to the pre-market move.
- Broader futures were modestly positive, offering limited confirmation of a market-wide explanation.
